“…The broad peak at 3390 cm −1 can be resulted from the stretching vibration of the -OH 23,50,51 bonded to the inter-lamellar water, the O-H groups of the adjacent layers, www.nature.com/scientificreports www.nature.com/scientificreports/ and even the physically adsorbed water 38 . The peak at 1632 cm −1 is corresponded to the -OH groups of metal hydroxide and the bending vibration of the interlayer water (δ H-O-H) 52,53 .

We aimed to obtain magnesium/iron (Mg/fe)-layered double hydroxides (LDHs) nanoparticlesimmobilized on waste foundry sand-a byproduct of the metal casting industry. XRD and ft-iR tests were applied to characterize the prepared sorbent. The results revealed that a new peak reflected LDHs nanoparticles. In addition, SEM-EDS mapping confirmed that the coating process was appropriate. Sorption tests for the interaction of this sorbent with an aqueous solution contaminated with congo red dye revealed the efficacy of this material where the maximum adsorption capacity reached approximately 9127.08 mg/g. The pseudo-first-order and pseudo-second-order kinetic models helped to describe the sorption measurements, indicating that the physical and chemical forces governed the removal process. The severity of water pollution has been resulted from the economic development adopted by human overall the world. The different industries such as textile, plastic, coating, and paper utilize the "dyes" in the different manufacturing stages 1-3 These compounds, even at extremely low concentrations can cause a significant contamination and, consequently, the destroying of the ecosystem elements 4-6. The continuous discharge of water contaminated with poisonous dyes to the environment can be formed a potential threat to the aquatic life and human health especially that the dyes are intrinsically toxic 7,8. Therefore, economical and highly efficient techniques need to be developed for treatment of the contaminated water 9-11. The presently available techniques include photocatalysis 12 , biodegradation 13 , chemical coagulation 14 , ion exchange 15-17 , and adsorption 18-22. The adsorption is one of the most valuable methods in the treatment of the aqueous solutions because of its high efficiency, ease of operation, low cost of operation, and easy desorption 23-25. The selection or fabrication of the adsorbents is the main operative point of adsorption, where these materials must be highly stable, low cost, environment-friendly, and definitely efficient 26,27. Until date, literatures have been reported different reactive materials containing activated carbon, zeolite, clay, chitosan, montmorillonite, and vermiculite 7. However, several disadvantages of these materials include the high cost, poor adsorption capacity, and low reuse rate, which limits their usage 28,29. Thus, finding more efficient, longer durability and low cost new adsorbents are a difficult but a vital task. Layered double hydroxide (LDH) is a type of layered anionic compound that is joined via a non-covalent bond-an interaction between non-framework interlayer anions and positively charged main lamellar. Its general formula is [M +2 1-x M +3 × (OH) 2 ] x + [An − x/n •mH 2 O] x − , where, M +3 is a trivalent metal ion such as Fe +3 , Cr +3 , Sc +3 , and Al +3 ; M +2 is divalent metal ions such as Mn +2 , Mg +2 , Ni +2 , and Zn +2 ; An − is an anion that balances the interlayer charge such as Cl − , OH − , NO 3 − , and CO 3 −2 ; x is the ratio of M +3 / (M +3 + M +2), var...

“…In this regard, photocatalytic technologies may be an economically feasible alternative. The application of photocatalytic technology to convert palm oil industry (POME) waste has shown good potential on a laboratory scale [49,117,120,121,[125][126][127]. Photocatalytic technology using either UV light or the sun is increasingly becoming a hot topic in research because it shows high efficiency in the mineralization of organic compounds and disinfection of pathogenic microorganisms in wastewater.…”

Photocatalytic Technology for Palm Oil Mill Effluent (POME) Wastewater Treatment: Current Progress and Future Perspective

et al. 2021

The palm oil industry produces liquid waste called POME (palm oil mill effluent). POME is stated as one of the wastes that are difficult to handle because of its large production and ineffective treatment. It will disturb the ecosystem with a high organic matter content if the waste is disposed directly into the environment. The authorities have established policies and regulations in the POME waste quality standard before being discharged into the environment. However, at this time, there are still many factories in Indonesia that have not been able to meet the standard of POME waste disposal with the existing treatment technology. Currently, the POME treatment system is still using a conventional system known as an open pond system. Although this process can reduce pollutants’ concentration, it will produce much sludge, requiring a large pond area and a long processing time. To overcome the inability of the conventional system to process POME is believed to be a challenge. Extensive effort is being invested in developing alternative technologies for the POME waste treatment to reduce POME waste safely. Several technologies have been studied, such as anaerobic processes, membrane technology, advanced oxidation processes (AOPs), membrane technology, adsorption, steam reforming, and coagulation. Among other things, an AOP, namely photocatalytic technology, has the potential to treat POME waste. This paper provides information on the feasibility of photocatalytic technology for treating POME waste. Although there are some challenges in this technology’s large-scale application, this paper proposes several strategies and directions to overcome these challenges.

POMSE's photocatalytic degradation system is below pH 6.5 in every 0.5 g/L ZnO-PEG for the 50% of POMSE dilution [Zainuri et al, 2018]. LaCa (3 wt% of La doped in Ca900 (calcium oxide)) as an opportunity photocatalyst because of extra greener and got here from renewable feedstock to update present photocatalyst.…”
